| 1 | Samsung ARM Linux Overview | ||
| 2 | ========================== | ||
| 3 | |||
| 4 | Introduction | ||
| 5 | ------------ | ||
| 6 | |||
| 7 | The Samsung range of ARM SoCs spans many similar devices, from the initial | ||
| 8 | ARM9 through to the newest ARM cores. This document shows an overview of | ||
| 9 | the current kernel support, how to use it and where to find the code | ||
| 10 | that supports this. | ||
| 11 | |||
| 12 | The currently supported SoCs are: | ||
| 13 | |||
| 14 | - S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list | ||
| 15 | - S3C64XX: S3C6400 and S3C6410 | ||
| 16 | - S5PC6440 | ||
| 17 | |||
| 18 | S5PC100 and S5PC110 support is currently being merged | ||
| 19 | |||
| 20 | |||
| 21 | S3C24XX Systems | ||
| 22 | --------------- | ||
| 23 | |||
| 24 | There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which | ||
| 25 | deals with the architecture and drivers specific to these devices. | ||
| 26 | |||
| 27 | See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information | ||
| 28 | on the implementation details and specific support. | ||
| 29 | |||
| 30 | |||
| 31 | Configuration | ||
| 32 | ------------- | ||
| 33 | |||
| 34 | A number of configurations are supplied, as there is no current way of | ||
| 35 | unifying all the SoCs into one kernel. | ||
| 36 | |||
| 37 | s5p6440_defconfig - S5P6440 specific default configuration | ||
| 38 | s5pc100_defconfig - S5PC100 specific default configuration | ||
| 39 | |||
| 40 | |||
| 41 | Layout | ||
| 42 | ------ | ||
| 43 | |||
| 44 | The directory layout is currently being restructured, and consists of | ||
| 45 | several platform directories and then the machine specific directories | ||
| 46 | of the CPUs being built for. | ||
| 47 | |||
| 48 | plat-samsung provides the base for all the implementations, and is the | ||
| 49 | last in the line of include directories that are processed for the build | ||
| 50 | specific information. It contains the base clock, GPIO and device definitions | ||
| 51 | to get the system running. | ||
| 52 | |||
| 53 | plat-s3c is the s3c24xx/s3c64xx platform directory, although it is currently | ||
| 54 | involved in other builds this will be phased out once the relevant code is | ||
| 55 | moved elsewhere. | ||
| 56 | |||
| 57 | plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs. | ||
| 58 | |||
| 59 | plat-s3c64xx is for the s3c64xx specific bits, see the S3C24XX docs. | ||
| 60 | |||
| 61 | plat-s5p is for s5p specific builds, more to be added. | ||
| 62 | |||
